Veil is a tool designed to generate metasploit payloads that bypass common anti-virus solutions.

Veil was designed to run on Kali Linux, but should function on any
system capable of executing python scripts. Simply call Veil from the
command line, and follow the menu to generate a payload. Upon creating
the payload, veil will ask if you would like the payload file to be
converted into an executable by Pyinstaller or Py2Exe.

If using Pyinstaller, Veil will convert your payload into an executable within Kali.

If using Py2Exe, Veil will create three files:

payload.py - The payload file

setup.py - Required file for Py2Exe

runme.bat - Batch script for compiling the payload into a Windows executable

Move all three files onto your Windows machine with Python
installed. All three files should be placed in the root of the
directory Python was installed to (likely C:\Python27). Run the batch
script to convert the Python script into an executable format.

Place the executable file on your target machine through any means necessary and don't get caught!
